Introduction

Under normal circumstances, astigmatism may be caused by heredity,不良 eye habits, trauma, glaucoma, cataracts, etc., and it can usually be corrected. In daily life, correction can be achieved through wearing glasses, special treatments, and other methods. It is also important to control the duration of eye use and practice proper eye habits, avoiding prolonged eye strain to allow sufficient rest for the eyes, which contributes to better eye health.

In general, astigmatism may be caused by heredity, bad eye habits, trauma, glaucoma, cataracts, and other factors, and it can usually be corrected. A detailed analysis is as follows:

1. Heredity

If there is a family history of astigmatism, the probability of offspring developing astigmatism is higher. If symptoms are severe, such as vision loss or visual fatigue, corrective eyeglasses should be worn under the guidance of a doctor.

2. Poor Eye Habits

Habits such as reading while lying down, excessive mobile phone use, or using the eyes in unsuitable lighting conditions may lead to astigmatism. In such cases, it is important to correct these poor eye habits, and frequently performing eye exercises may help alleviate symptoms.

3. Trauma

If the eye sustains trauma, it may cause lens dislocation or subluxation, which can lead to astigmatism. It is recommended to seek adjunctive treatments such as acupuncture and massage under a doctor's guidance, as these may promote blood circulation and aid in correction.

4. Glaucoma

Glaucoma may be caused by heredity or trauma, among other factors. If not treated promptly, it may lead to astigmatism and may also be accompanied by symptoms such as eye pain and headache. Medications such as acetazolamide tablets, mecobalamin tablets, and methazolamide tablets may be used for treatment under medical supervision.

5. Cataracts

Cataracts are a visual impairment condition caused by clouding of the lens, which may result in varying refractive indices across different regions of the lens, leading to astigmatism along with vision loss. Treatment may include medications such as vitamin C chewable tablets, Fuming tablets, and glutathione tablets, used in accordance with medical advice.

In daily life, astigmatism can be corrected through the use of glasses or specialized treatments. It is important to manage eye usage time and adopt proper eye habits, avoiding prolonged eye strain to allow sufficient rest for the eyes, which is beneficial for overall eye health.
